[SOLVED] detect X11 user inactivity

Question

Hi there,
I want to write a script that shuts down the computer if I don't use X11 keyboard and mouse and no video player is running after 12PM. I hate waking up in the morning with the computer running after falling asleep during a movie.
How can I detect if I'm using X11? Is there any way to check if dpms kicked in or the mouse and keyboard aren't used for some time? Or some screensaver can tell over dbus if it's active or not? (right now i don't use any screensaver, only X11 dpms).
Pidgin has a way of detecting user inactivity based on keyboard and mouse usage, so probably there is a way to do this. Any ideas?
Thanks a lot!

Answer 1

18 lines of C...
/* gcc -o getIdleTime getIdleTime.c -lXss */
#include <X11/extensions/scrnsaver.h>
#include <stdio.h>
int main(void) {
Display *dpy = XOpenDisplay(NULL);
if (!dpy) {
return(1);
XScreenSaverInfo *info = XScreenSaverAllocInfo();
XScreenSaverQueryInfo(dpy, DefaultRootWindow(dpy), info);
printf("%u", info->idle);
return(0);
